Patent CA-2749935-A1 (CA)
Inventor: TODOROVIC ALEKSANDAR
IPC: B01F23/00
Filed: 2010-02-08
Abstract: The invention provides a method and apparatus for optimally feeding an ASA  emulsion into a papermaking process. An intense transmission of ultrasonic energy rapidly and efficiently forms an ASA emulsion. Nearly simultaneous to forming the emulsion, the emulsion is fed into a high-speed dual conduit feeding apparatus (12), which quickly mixes the ASA emulsion with other chemicals and feeds the mixture directly into a papermaking process. The invention operates so fast that virtually no hydrolysis of the ASA occurs. This both prevents damage to the papermaking machinery and improves the quality of the produced paper. The invention operates 10-20 times faster than mechanical based emulsion methods and requires 1/7 as much energy to operate. The invention also self-monitors the process and can automatically correct any detected problems with the fed ASA  emulsion.
Patent CA-2750241-A1 (CA)
Inventor: NIELSEN JAKOB
IPC: G10L21/0264
Filed: 2009-01-20
Abstract: A hearing aid has means (15) for detecting fast transients in the input signal and means (16, 12, 13) for attenuating the detected transients prior to presenting the signal with the attenuated transients to a user. Detection is performed by measuring the peak difference of the signal upstream of a band split filter bank (11) and comparing the peak difference against at least one peak difference limit.  Then, if a transient is detected, a state machine (20) analyzes the peak level and the absolute average level of the signal and engages a gain calculator (12) to follow either the peak level or the absolute average level of the input signal for at least the duration of the transient in order to attenuate the transient. The engagement of the gain calculator (12) is performed in each frequency band dependent of the detected transient. The invention further provides a method for detecting fast transients.

Abstract: An OVPN user register an L-1 signal type information which is used in the user's device in an OVPN terminating device in advance together with an IP address and a VPNID  which are allocated to the user's device. Registered contents are notified to other OVPN  terminating devices which control the same VPNID as that of the user's device.    Otherwise, when a calling connection request arrives from the user's device, the registered contents are notified to other OVPN terminating devices which control the devices which receive the notification. By doing this, it is possible to handle a request by the user for changing the setting for the signal format which is employed in the user's device quickly. Also, it is possible to realize an OVPN which can perform a process for a calling connection request from the user efficiently and improve an operability for the user.
